[Linuxptp-users] PPS Error: PTP_EXTTS_REQUEST2 failed

[Deshpande, Y. <yas...@tu...>]

Dear all,


I have 2 intel i210 NICs and I want to enable one as a PPS source and the other as a PPS sink.


I get the PTP_EXTTS_REQUEST2 failed: Operation not supported error when running ts2phc.


Am I doing something wrong? Should I be using some special driver to make this work?


Some outputs are:


  1.  ethtool -i enp1s0


         driver: igb
         version: 5.15.0-43-generic
         firmware-version: 3.25, 0x800006eb, 1.1824.0

     2.  uname -r



          5.15.0-43-generic

     3.  sudo phc_ctl enp1s0

          phc_ctl[17465.576]:
